Enter up to four compound names. Use the autocomplete functionality to
select a full compound name, as no substring matching is done on compound
names. Note that the autocomplete mechanism only shows compounds that are
actually consitituents of one or more growth media.
Examples: "L-arginine", "beta-D-glucose"

Search/Filter by compounds not present in the medium

Find Growth Media that do not contain any of the following compounds:

Search/Filter by observed growth

Find growth media for which any of the checked growth levels have been observed. Note that this will exclude all growth media for which no growth observation data is available.

Growth
Low Growth
No Growth

With Gene Knockout (leave blank for wildtype):

Check or uncheck the growth level boxes as appropriate. If no gene knockout
is specified, then media on which the wildtype organism exhibits one of the
specified growth levels will be returned. When specifying a gene knockout,
use the autocomplete functionality to select a full gene name, as no
substring matching is done on the gene name.
Examples: "trpA", "hisC"
Note that only a small proportion of growth media currently have gene
knockout observation data.

Note: Only search criteria that have been checked will be used in constructing the query. If multiple search criteria are specified, then results must satisfy ALL of them.
